Durin did not dine at Mentor Cherny's house.
Nor was there a crisis that required Durin to step in; it was just that Tanya from the Algin family invited Durin to visit her home.
Of course, not the one in Copenhagen, but at the Algin family's estate near the Sidney Union, near the ancestral homeland of their family. It's said that there was a large hill there, atop which sat the Algin family's vast villa and estate.
There were lakes, slopes, and cliffs, and it is said that the Algin family "resisted" Sidney's army right there—of course, that was after the Northern Kingdom's troops had withdrawn from the Sidney Union.
In any case, even now, the area is still dotted with a large number of watchtowers and fortresses, and the Algin family even installed artillery batteries on their estate.
